Application filed January 22,1908. Beri al No. 412,144.

To all whom'it ma'y 'concem: y

. Be itknown that I, PAUL F. VoeEL, a citizen of the United States, and a resident of Clinton, in the county .of Anderson and State ofTennessee, have invented anew and 1mproved Machine for Unraveling Textile Fabrics, of which the following is a full, clear, and exact description. Z I

I This invention relates tomachines-for unravelin textile fabrics, and moreparticularly 'to mac ers,:and serving for unraveling the selvage edges of knitted hosiery.

An object of he mvention is to provide a simple, inexpensive. and efficient mechanism to be used in combination with loopers which so for join together edges of knit goods, and serving to unravelthe selvag'e' edges of such goods and to wind the unraveled yarn upon a reel.

A further, object of 1 the invention is to'provide a device of the class described adapted to be mounted upon a looper and to be operated by the drivin mechanism of the loo er. A still further 0 jectof the invention 1s to rovide, in combination with a looper hay-- mg means for holding the fabric, a reel, means for operatively connecting the reel with'the drivm mechanism of the loo er to operate the ree and means upon the ooper guidingthe yarn to be unraveled, from the abric onto the reel. 1,

- The invention consists inthe construction male claims.

4c and in which ing'my invention applied thereto'yFig. 2 is a and combination of parts to be more fully described hereinafter and particularly set forth Reference is to be'had 'to the accompanying drawings forming a part of this specifica-,

tion, in which similarcharacters of reference indicate corresponding parts in all the views,

. Figure '1 is a side elevation of aloo'per hav planview'fofthe looper with theunraveling machine; and Fig. 3 is a front elevation: showing the reel an'dfthe guiding mechanism of the unraveling machine.

Before proceeding; to a more detailed ex lanation of m invention, it should be unerstoodzthat" e; same is particularly useful 5 0. with'loopers. .Loopersiare those machmes which are employed Itojjoinedges of seamless; stockings, to'

goods. For example, im'hosiery, knitpr woven, it s customary, manufacturing eav a. gap. 'or o enin'g across the toe. Theloo'per s use 'for es-used in combination with loop .The arm 37 is actuated closing this gap, or for any other work in knit goods manufacture where two ed es are to be joined together. The edges 0' not always meet exactly, and itis therefore nec-' essary -to unravelpart of one or the other,

when the fabric is m the looper. Often, the,

yarnunraveljed from the fabric in this way'is wasted, and as. the unraveling is generally performed by hand, it is'a tedlous operation which involves considerable loss of time My invention is for the purpose of automatica1 y unraveling these superfluous or selvage 1 edges of the fabric, while the same is on the looperand is being operated upon therebly. I provide common means for driving t e loopeLand the unraveling mechanism; that is, the latteris actuated directly from the driving mechanism of-the loo er.

Referring more particular y,to the drawings, 10 represents a'looper, which may beof any. preferred or common type. The looper is mounted in any convenient manner upon a supportll, and has holdin I members 12 rovided with bearings 13 whic cair'y a drivmg shaft 14. The-latter has a hand crank 15 by mea'nsof which it can'be operated, or 'it The looper comprises a needle blade 16, which is preferably inzthe form of a-disk'ha'ving its periphe outwardly beveled and containing tially central hub 17 which is mounted upon a supporting arm 18. An annular clamping member. or rin 19 is arranged at the periphery of the nee le blade, and serves to clamp the stocking 20 or other fabric in position, to permit the needles of the looper to operate suitable manner.

' can be driven in any other suitable manner.

. the nee lesandoperating mechanisminot shown); The needle blade 16has a substanthereupon. A looper operating ratchet wheel i 36 is carried, by the blade 16 and is actuated p the wheel-36,

-means ofa screw or bolt 22, or in any other The frame. 21 has up-I wardly disposed-arms. 23, forming bearings.

in which is journaled ,the reel shaft 24. "The latterhas sides 25 joined by the reel bars 26,

. upon which the yarn 28, unraveled from the fabric 20 is-wou'n'd. At one side of the reel,"

the shaft 24; has a'rigid pulley 29, connectedby means of a belt 30,-with a pulley 31 rigidlymounted upon the shaft 14. The shaft 14, it Will be understood, is the drivin shaft which operates-the mechanism of the ooper.

A curved guide plate 32 is mounted upon the upper face of the needle plate 16, and at one end is formed into a knife 33 for severing the yarn when the fabric has been sufficiently unraveled. A correspondingly curved guide bar 34 is arranged at the forward side of the guide plate and is separated slightly therefrom. The guide bar is held in position by means of supporting arms 35 extending from theframe21;

The stocking or otlrenfabric 20 is clamped in position uponthe looper by means of the ring 19, the edgesto be joined being properly positioned for the purpose. By turning the and crank 15 or by driving the shaft 14 in some other manner, the looper is operated to join the edges of the fabric and at the same time to unravel the selvage and wind the yarn therefrom upon the reel. course, first necessary to start the unraveling It is of and secure the end of the yarn to the reel, the guide plate 32 and the guide bar 34 serving to guide thefyarn as it is wound upon the reel,

. being "suitably curved to facilitate the even disposal and the smooth unraveling of the yarn.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent: 4

1. The combination, with a looper, of means for holding the fabric to be Worked upon by the looper, means for unraveling the selvage of the fabric, and means for simul taneously operating said looper and said unraveling means ,said looper having means for bar adapted to' cooperate with said guide plate to direct yarn from the fabric to said reel. a

4. In combination, means for holding a fabric, a reel, meansforoperating said reel, and means for guiding yarn from the fabric to said reel, said guiding means including means for severing the yarn.

5. In combination, means for holding a fabric, a frame, a reel rotatably mounted upon said frame, a guide plate having a part constituting a knife, said frame having arms, a guide bar carried by said arms and arranged adjacent to said guide plate, said guide plate and said guide bar serving to direct the yarn from the fabric to said reel, and means for driving said reel.

In. testimony whereof I. have signed my name to this specification in the presence of two subscribing witnesses.
